Paul tells us:
For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh. But he is a Jew who is one inwardly; and circumcision is that which is of the heart, by the Spirit, not by the letter; and his praise is not from men, but from God.
Romans 2:28-29
In short, the only real Jews in the Christian Era are Christians. After all, the religion of Moses is now called Christianity.
